Feline idiopathic cystitis (FIC) is a stress-sensitive bladder condition in cats that causes painful urination and is strongly linked to environmental stressors, making welfare management central to treatment and prevention.
FIC exemplifies the profound connection between psychological welfare and physical health in cats. The pain of urination with FIC — straining against an inflamed bladder — is genuine and significant, but the root cause is often chronic environmental stress rather than primary bladder disease. Cats in multi-cat households with resource competition, cats denied adequate territory and escape routes, or cats whose routine has been disrupted are at highest risk. Treatment that addresses only the acute episode without identifying and modifying the underlying stress sources leads to predictable recurrence. The welfare approach to FIC therefore requires a thorough environmental audit: litter box number and placement, feeding station distribution, hiding places, vertical territory, human interaction patterns, and sources of anxiety. Resolving FIC permanently requires resolving the welfare deficits that drive it.
